The Problem With MRI

CNN's John Sutter looks at the potential dangers of mind reading using MRI scans. He says some experiments have been done to see if people can tell which objects they are looking at by patterns in their brain scan. But he argues that this is a far cry from real mind-reading, and it doesn't hold water for visual protection. The use of lie detector tests has also raised concerns about what might be possible with an MRI scanner on the human brain," writes Sutter.
